Abstract: ABSTRACT OF DISCLOSURE           Full-range shale oils or fractions thereof, after hydrotreating,  are hydrodewaxed and then hydrogenated to produce  lubricating oil  fractions  boiling above  650° F. (343°C.),  having  a  pour  point  at  or  below  +10° F. (-12.2° C.), and a viscosity index of at least 95.  In the preferred operation, the hydrogenation is effected with a noble metal-containing catalyst wherein the noble metal is dispersed by cation exchange into a carrier comprising a silica-alumina cogel or copolymer dispersed in a large pore alumina gel matrix.  It has been found with shale oils that the hydrogenation in the preferred embodiment also results in hydrocracking of some of the polynaphthenic compounds. Since polynaphthenic compounds can contribute to or them-selves cause low viscosity index in lubricating base oil, the invention is believed particularly applicable to those feedstocks, not necessarily of shale origin, wherein it is desired or necessary to raise the viscosity index by hydro-genation with simultaneous hydrocracking of polynaphthenic compounds.

Granted: 1992-05-26
Abstract: ABSTRACT OF THE DISCLOSURE             A centrifugal separator for gold or the like is of the type in which a bowl is rotated at high speed so that materials fed into the bowl pass over the peripheral wall of the bowl to an open mouth.  On the inner surface of the bowl is provided a series of ribs defining peripheral recesses in which the heavy material is collected.  An outer shell surrounds the bowl and defines with it a chamber into which water is injected to  pass  through  openings  at  the  base  of  the  recesses  to fluidize the material within the recesses.  The outer shell has a peripheral wall of increasing diameter toward the open mouth with a plurality of openings being provided in the shell around the open mouth to allow the escape of silt collecting in the chamber.  A wear resistant plastics material is attached to the bowl  at  the open mouth and to a casing surrounding the open mouth to redirect the exiting materials to an outlet duct.   A plug for the base of the bowl can be latched into place by a pivotal  latch member actuated by centrifugal force caused by rotation of the bowl to prevent loss of the plug under the high forces generated during the rotation.

Title: High voltage regulator in a television apparatus
Inventor: STEPHENS JOSEPH C
IPC: H02M3/28
Filed: 1989-04-06
Granted: 1991-11-26
Abstract: ABSTRACT A switch regulator includes a controllable SCR switch that is coupled in series with a filter inductor and a horizontal deflection generator.  The series combination is coupled across a source of unregulated direct voltage for providing a path for an increasing current flow in the inductor during a portion of a trace interval in which the switch is closed.  Horizontal rate signals are coupled from the deflection generator to the switch via a first winding for controlling the time at which the switch becomes non-conductive.  A catch diode is coupled to the filter inductor to form a path for a decreasing current flow in the inductor during at least a portion of a retrace interval. The first winding is coupled in series with a second inductor to form an arrangement that is coupled between the unregulated voltage and the SCR switch.  A current in the second inductor maintains the switch conductive during a portion of retrace that varies in accordance with a beam current for improving regulation of an ultor voltage.

BROWN                             ABSTRACT A liquid-containing paperboard laminate carton including a one-piece plastic  spout having  a pair of opposing flanges  sealed about an aperture in one of the carton walls to both the innermost and  outermost  surfaces  of  the  carton  wall.   The  double  flange configuration  not  only  forms  a  mechanically  positive  interlock between the  plastic  spout  and  the  carton  wall,  but  even  more importantly, isolates the cut edges of the aperture from exposure to liquid either  from within the container  or from the  environment through which the carton must pass from the point of manufacture until it is ready for disposal after its contents have been consumed. The  spout  preferably  includes  a  liquid  passageway  having  a membrane-type seal across its discharge orifice to provide evidence of tampering and a resealable closure member such as a screw cap or a snap-on closure held in place by means of a mating ring or groove on the spout.  The cross-sectional area and configuration of the liquid passageway and discharge orifice in the spout are designed to prevent complete blockage by liquid when the package contents are being dispensed during a normal dispensing cycle, i.e., when the package is not being held completely upside down.   Method and  apparatus  for securing said one-piece spout in sealed liquid type relation of both surfaces of the carton wall either sequentially or simultaneously are also disclosed.

Abstract: The invention is concerned with a process for preparing ciprofloxacine of the formula (see fig.I) based on the reaction of 1-(2,4-dichloro-5-fluoro-phenyl)-1,3-butanedione with ethyl orthoformate, to give an enol ether which is reacted with cyclopropylamine, resulting in an enaminone, the cyclization of which provides a compound which is reacted with N-ethoxycar-bonylpiperazine, producing an intermediate, whose oxidation leads to an acid which provides ciprofloxacine by means of alkaline hydrolysis and neutralisation. Ciprofloxacine is a highly affective bactericidal agent against gram-positive and gram-negative bacteria.
